Eyes large and situated closer to the tip of the snout than to the posterior end of operculum; eye diameter always smaller than interorbital width (Ref. 80507). Mouth small and subterminal (Ref. 80507). Upper jaw with a single row of 8-10 bicuspid, acute teeth; upper jaw teeth limited to the premaxilla (Ref. 80507). Body covered with ctenoid scales; lateral line complete and originating midlaterally behind operculum; two or three lateral line scales extending of on caudal fin (Ref. 80507).
